Hi mushroom and welcome to the vine (or madhouse). They can be used both fresh and dried. I would stick to fresh with anything hardy e.g. sage, thyme, rosemary and explore the options with the tender stuff. As suggested you could freeze, dry or pot up for overwintering indoors. You could also try fennel which is usually made from the dried seeds. One plant should provide most of your needs.

When things are available fresh best to use them that way and capture the best the plant can provide.
